First round of chlomid

[Lotsofbabiesplease]

Hi ladies I thought I would start a new thread as it is so hard to find an 'in-date/active' thread.
I was put on chlomid because my clycle length is 34 days and have pcos. (the smallest form) me and my other half have been trying for a year this march after sadly losing out baby at 20 weeks.
I started my first round of chlomid this month (day 2-6) and am currently day 15 of cycle. Can anyone tell me if I should be getting side effects now? I'm getting very dizzy (with low blood pressure) bad tummy aches and quite bad fatigue! Oh and loss of appetite. I've been booked in for a blood test 10 days before af is due, does this sound right? Lots of ladies seem to be having blood tests sooner then this.
Hopefully someone can shed some light on this.
Thank you xxx
